FILLING DEVICE.

Application filed June 11, 1921. Serial No. 476,698.

To all whom it may concern:

Be it known that I, EARL H. WISEMAN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and usefulImprovement in Filling Devices, of whichthe following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to filling devices and is directed more particularly to a devicefor filling storage batteries.

Some of the objects of the present invention are to provide a filling device whichmay be easily attached to a reservoir such as a bottle and which shall be automatic in control, that is, the bottle may be inverted and the device entered into the vent opening of a storage battery, after which, liquid from the reservoir will flow into the battery until it reaches a predetermined height when it will be automatically shut off and the device may be removed and inserted into the next vent opening; to provide a device of the aforesaid character which shall include means for shutting oii the flow of liquid from the reservoir when the device is removed from the battery but which shall automatically permit a free flow of liquid when the device is inserted into the battery vent opening; to provide a device which shall accomplish the foregoing results and which shall be simple in construction and inexpensive to manufacture, while further objects and advantages will appear as the description proceeds.

In the accompanying drawing wherein I have shown one form of my invention, but without intent to limit myself thereto, Fig. 1 is a vertical sectional view of my device showing it attached to the neck of a bottle; Fig. 2 is a similar view but taken at right angles to Fig. 1, and Fig. 3 is an enlarged sectional view taken on the line'33 of Fig. 1.

Describing by reference characters, the various parts illustrated 1 indicates the body portion of my device which is preferably acid proof and which may be a casting formed from an alloy of lead and antimony similar to that used for storage battery plates, or which may be formed from bakelite, hard rubber, or other suitable acid resisting material. A central longitudinal opening 2 extends through the body portion gitudinally in the bore 2, and also serves to' space the lower end of the device from the battery plates and permit a free flow of liquid through the bore 2. The upper end of the valve stem 4 is provided with a suitable valve head 5, the purpose of which will be more fully set forth hereinafter.

On each side of the central bore 2 I provide a smaller opening 6 which extends from the upper end of the body portion, downwardly to a predetermined point adjacent the lower end of said body portion, at which point the bores 6 emerge through the side walls as clearly shown in Fig. 1. The point at which these bores emerge through the side walls is determined by the depth of electrolyte desired above the battery plates as these bores serve to automatically check the flow of liquid into the battery when the liquid seals the lower ends thereof thus preventing air from entering therethrough to the reservoir. The upper end of the body portion is tapered as indicated at 7 and an annular shoulder 8 is formed at the large end of said taper. A gasket 9 formed from cork, rubber or other suitable material is fitted over the tapered end 7 and into contact with the shoulder 8 so that the device may be conveniently and easily inserted into the neck of a bottle. In practice I preferably extend the gasket 9 slightly above the tapered end of the body portion and in this manner I form a seat for the valve head so that said valve may contact therewith and close the bores 2 and 6. WVhen the valve stem 4 is made of metal or other conducting material'I preferably provide the lower end thereof with a suitable insulating bushing 10 to prevent said stem from shortcircuiting the battery plates.

In operation the device is inserted in the neck of a bottle of liquid with which the battery is to be filled and the bottle is then inverted. The valve 5 will immediately engage the gasket 9 and prevent the liquid from escaping. When the valve is closed, the valve stem projects a short distance below the web 3 and when the device is inserted in the batter opening the valve stem will contact with the battery plates and'be pushed upwardly until it contacts with the web 3. The upward movement of the valve stem unscats the valve and liquid flows down through the central bore 2 into the battery. and air enters through the openings 6-6 and is admitted into the bottle. The liquid will continue to flow into the battery until 1 it seals the openings 6-6 in the side walls of .the device, after which the flow will stop antomatically since the air'supply will be shut off from the reservoir. It might be noted in this connection that the operator can determine when the liquid has stopped flowing since air bubbles will cease to rise from the upper ends of the openings 6-6. .The device is then lifted from the battery vent opening and the pressure of liquid on the valve head 5 and the weight thereof will cause said valve to engage its seat and seal the neck ofthe reservoir.

While I have shown and described my device for use in connection with storage batteries it will be understood that it may be used for other purposes and that various changes may be made therein so long as such changes remain within the scope of the ap pended claims.

Having thus described my invention, what I claim is:

1. A battery filling device comprising-a body portion having one end thereof operatively connected with a container, a plurality of bores extending longitudinally through said body portion and communicating with said container, certain of said bores being adapted to conduct li uid therethrough from said-container,'t1e other of said bores being adapted to conduct gases through the liquid into said container there; by to indicate when liquid is flowing into the battery, said liquid conducting bore being located adjacent to but projecting beyond said gas conducting bores at the. end of said body portion opposite said container,

valve means associated with the end ofsaid bores connnunicating with said container, and a valve stem connected with said valve and projecting through and beyond said body portion, said valve stem being adapted to contact with a surface to unseat said valve when said device is used to fill a battery thereby to permit liquid from said container to flow through said liquid conducting bore.

2. A battery filling device comprising a body portion having a liquid conducting boreand a vent bore extending longitudinally therethrough, said liquid conducting bore being located adjacent to but projecting beyond said vent bore at one end of said body portion, and a valve adapted to close said bores and having a valve stem projecting through said liquid conducting bore and extending beyond the end of said bore opposite said valve.

3. The combination with a transparent reservoir, of a filling device operatively connected to said reservoir and comprising a body portion having a bore extending longitudinally therethrough, a valve stem extending through said bore, a valve carried by one end of said, stem, the opposite end of said stem being enlarged and proiecting beyond said body portion, the enlarged end of said valve stem being adapted to contact with an object to unseat said valve, said body portion being provided with a vent port adjacent to but spaced from the enlarged end of saidvalve stem, and means for conducting the gases from said vent port to said reser voir, said gases being adapted to rise through the liquid in said reservoir during the flow of liquid therefrom thereby to ad vise the operator when said liquid has ceased flowing.

In .testimony whereof, I hereunto atfix my signature.

EARL H. WisEMAu.
